         The <code class="methodname">DBcursor-&gt;dup()</code> method creates a new cursor that uses the same
         transaction and locker ID as the original cursor.  This is useful when
         an application is using locking and requires two or more cursors in
         the same thread of control.

                When a client synchronizes with the master, it is possible for committed
                transactions to be rolled back. This invalidates all  the database and cursor
                handles opened in the replication environment. Once this occurs, an attempt to use
                such a handle will 
                
                return <code class="literal">DB_REP_HANDLE_DEAD</code>.
                The application will need to discard the handle and open a new one in order to
                continue processing.
